But I was curious! Have you ever painted your tank's background? If so, what colors do you think would work with his color pattern? My husband and I have been on a vampire kick for the last few years, so we'd like it pretty dark/eerie in there. But I wasn't sure if BLACK was the way to go... There are going to be quite a few green plants and a silver castle in there as well. So I don't need a super intricate background.

I'd love to see everyone's, if they have any examples of what they did/bought.

slate blue?kind of a moonlight color, and then have a cool lighting option for night? i am looking into backgrounds for my 40 gallon. i may try rice paper window film from home depot. they have stained glass film as well.

I've thought about drops of glow in the dark paint put directly on the tank, and then dark blue or black after those dry. From the outside, it would look like a solid color. From the inside, hopefully it would be speckled with glow in the dark dots. Might give a cool "starry sky" effect when the lights are out. Might be a total failure. Haven't tried it!

Myates: That's my primary concern, I'm almost thinking a light slate-ish blue? I've tried out the black/red combo and I'm not sure I'll be happy with it when he's inside. It makes the plants pop; but I want to make sure HE pops. ;)
